Q:

Check gauges on 2002 Chevrolet Trailblazer

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
just noticed that my check gauges light would go on then cut off back and forth. I looked at my gauges and noticed that my oil pressure gauge will be fine then fall then jump back to normal. What do you think?

When I am idleing it drops , then when I give the gas it jumps back to normal ...... Is an oil pressure switch expensive usually?
